GAS-STOV E.

SPECIFICATION forming part of Letters Patent No. 337,379. dated March 9. 1886.

Application filed April 6, 1885.

Serial No. 161,269. (No model.)

To all whom it may concern:

Be it known that I, JOHN CLINGMAN, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Gas- Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to gas-stoves for heating; and it consists in certain details of construction, as hereinafter pointed out and claimed.

The bject of the invention is to produce a gas-stove which shall present a very large radiating-surface for heating, and which shall have a free circulation of the heated currents produced by combustion.

In the drawings, Figure l is a central longitudinal section of a stove illustrating the principles of my invention. Fig. 2 is a perspective view, parts being broken away to show the internal construction. Fig. 3 is a horizontal section on line mm. Fig. 4 isa partial elevation of a modification.

A designates the top of the shell or outer casing of the stove; B, the back plate of the same; 0, the bottom plate.

The burners are shown at D, and the gassupply is conveyed to said burners in any suitable manner.

The burners are located under the arched crown-sheet E, which is extended around behind the burners and forward to the front of the stove at F.

Between the front of the crown-plate E and the top plate, A, there is a passage, a, into which the heated air and products of combustion are drawn. This passage extends the full width of the stove, and leads down the passage 12 at the back of the stove, being I separated by plate G from the central chamber, H. The passage 0 leads forward to the front of the stove, plateKforming a partition between the same and the chamber H. The sides of the passage 0 are cut off for a part of the distance at each side by the partitions L L, which form return-fiuesdd from the front cylinder, M, to the chamberI-I; or, inlieu of these partitions, pipes L may beemployed.as shown in dotted lines, Fig. 3. The heated air and gases enter the chamber H through suitable passages, as at e e. The contained air in this chamber, being rarefied by the heat passing will be prevented from escaping at the ends of the arch, and will enter the passage Over the crown-sheet, and so pass, back under the top plate of the stove.

It will be seen that the heated air and products of combustion pass almost entirely round the stove in contact with the exterior surface in a broad thin film, and then enter an expansion-chamber before passing out of the stove. In this manner avery large heating-surface is obtained and very complete combustion of 7 gases secured, while a good draft and ventilation are secured by the presence of the expansion-chamber. The heated air and products of combustion from the burners fill the space above the burners, and, being prevented from escaping from the ends of the arch by the side plates of the stove, will pass into the fiat passage at the front ofthe arch, and so up in contact with the exterior plates of the stove, and at the same time in contact with the expansion-chamber. This secures alarge radiatingsurfaoe and a good draft. Air to supply the burners follows the curve of the front plate, and is somewhat heated before reaching the burners.

It will be understood that the external ap pearance of the stove may be changed somewhat, either in form or ornamentation, so that i the general arrangement conforms to the spirit of my invention.

I claim 1. A gas-stove having an expansion-chamber, one wall of which forms an arch, burners under said arch, and a passage leading from one side of said arch over the same and ultimately into the expansion chamber, and an outlet-pipe leading from said chamber, as set forth.

2. The combination, with an expansionchamber, one wall of which forms an arch, of a series of burners under the arch, side plates which close the ends of said arch, and a passage from one side of the arch leading over the same and ultimately into the expansion-chamher, and an outlet pipe leading from said chamber, substantially as described.

3. The combination, with the expansionchamber having its front wall forming an arch, of a flat passage from the front of the arch over the expansion-chamber, down at the rear of the stovein proximity tothe chamber, and finally entering said chamber, an outlet-pipe from said chamber, and a series of gas-bur'ners under the arch, all substantially as de- Scribed. A

4. in a gas'heating stove, the combination,

with anexpansion-chamber having one of its faces exposed to the atmosphere, of the burners, apassage from said bu rners over the chamher, down behind said chamber, forward underneath said chamber to the extreme front of the stove, and separate passages from each side thereof'leading backward and upward in to the expansion-chamber, and an escape-pipe from said expansion-chamber, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN GLINGMAN.
